    All of the vendor provided sizing software for hot water is aimed at
    daily use, not peak.  "Recovery Time" is usually provided for hot
    water and<br>
    <br>
    that can be flipped over to give a good estimate of peak use, but
    only for hot water.<br>

    In fact the fairly-early-in-the-day demand for hot water in K-12
    education food service limits the effectiveness of Solar Thermal
    systems somewhat.<br>
